Just for anyone else who needs this. Plugin editor -> functions.php line 918 in the code. Change service_city, state etc to the proper field ID created on the “Form Fields Settings” page in the plugin UI. I needed a “delivery Method” returned and made it a choice and set it as the “description” id optional one that shows on receipt. I made the “invoice_number” the recipient email address which also shows on the receipt. Not perfect but it does the job for my purposes. Thanks again to the dev.
I noticed that the issue doesnt exist in firefox, but all chrome browsers have this problem. I’m not sure its something related to the iframe implementation specific to chromium.
